My landlord insurance covers tenant accomodation in the event of something like this for up to a year. But that’s me being nice.
What insurance has your daughter got? It may be she has to try and fight a corner for compensation.
Had this when i first moved into a flat, tennant above offered to pay for repairs etc and claim them back off her insurance as it was her side of the flat stop tap, as opposed to the communal stop tap outside on the car park.
If its the landlords side of the stop tap his or her insurance should pay thats if they have the relevant insurance.
Take loads of pictures etc of the damage try to lift stuff off the floor and away from drips and leaks, plastic sheeting and bin bags all help..
I m a landlord and when i took out insurance for a rented flat the broker told me i had no liability for any claims against me from say neighbours. My plumber flooded downstairs and though and repaired the damage.
The rental contract stipulates whether the landlord has to provide alternative accomodation in the event of flood, fire etc.
Usually the person who has suffered the loss (in this case the tenant & their landlord) need to claim on their insurance, and their insurers will seek to recover the costs from the insurers of the policyholders whose flat had the escape of water.
